The eye can be taken a look at with relative ease as to both its function and its structure. A practical evaluation consists of the ability to relocate the orbit and the response of the student to light and accommodation.
The function of the eye might be evaluated in several ways. The patient may be asked to identify illuminated letter or items of differing sizes on what is known as the Snellen chart.
Conversely, the evaluation of the structural part of the eye may be made in a number of methods. Tension within the eyeball is determined by a "tonometer." In particular diseases, particularly in glaucoma, the stress in the eyeball is increased markedly.
However, it ought to be well bore in mind that a patient with an eye problem may have other issues too. Often other physical conditions are primary and affect the eye as a repercussion. The appearance of the eye can notify the doctor and the client to difficulties in some disturbances of other parts of the body even prior to other signs provide themselves.
Consequently, one's dependence on sight is highlighted when one deals with a short-term or possible irreversible loss of this vital sense. When corrective measures are sought, particular types of vision correction such as contact lenses or eyeglasses are recommended.
On the other hand, some people are troubled with that they have some framed lenses or contact lenses in front of their eyes.
For this factor, advanced surgeries were established to motivate reduced usage of contact lenses or glasses. One of which is the now popular LASIK eye surgical treatment.
Basically, LASIK eye surgical treatment is the short term for "Laser-Assisted In Situ Keratomileusis." Like its concrete counterpart, LASIK eye surgery is another kind of vision correction. The only difference is that with this kind of surgery, one's vision is fixed completely.
With LASIK eye surgical treatment, the refractive errors in the cornea are completely changed. This can be done using an "excimer laser."
The primary function of this surgery is to develop a threadlike, rounded "flap" in the cornea utilizing a blade referred to as "microkeratome." In a series of unfolding and laser processing, the cornea is finally reformed, allowing much better the eye to direct more light into the retina.
Appeal vs. Disadvantages
In the middle of the growing appeal of LASIK eye surgery, there are still disadvantages that individuals must know. Probably, the main reason that this type of eye surgical treatment has actually become well accepted is due to the fact that the majority of its cases had achieved success.
Nevertheless, in spite of its success, there are still some disadvantages. Here is the list:
1. It is an operation applied to the most delicate part of the eye
Because LASIK eye surgical treatment includes the operation of the retina, which is one of the most delicate portions of the eye, many people state that the operation can be very dangerous.
Simply puts, a simple error might almost trigger an individual's life time blindness. Hence, it is necessary to consider numerous factors before choosing whether LASIK eye surgical treatment is the ideal corrective measure one has to go through.
2. It is not a ideal procedure
LASIK eye surgical treatment may remedy your vision but it does not necessarily mean that it can give you a perfect vision. Even if statistical reports show that 70% of the patients may have 20/20 vision, this does not always suggest they have perfect vision.
Given all these things, it can be deduced that, in spite of the appeal of the operation, LASIK might not constantly be the perfect eye surgical treatment the way the majority of people see it
Alternatively, the examination of the structural part of the eye might be made in numerous methods. It ought to be well kept in mind that a patient with an eye problem might have other issues. Typically other physical conditions are main and impact the eye as a effect. The look of the eye can signal the physician and the client to troubles in some disruptions of other parts of the body even prior to look these up other symptoms provide themselves.
Like its concrete counterpart, LASIK eye surgery is another form of vision correction.
